BATHTUB TABLE.

Application filed January 2, 1925. Serial No. 278.

My invention relates to tables for supporting bath tubs while siftingthereon the powdered material for enameling and the object of myinvention is to provide a simple and entirely efficient mechanism bywhich the tub may be caused to occupy the great number of positionsnecessary to present its surface properly in position for the siftingoperation.

My invention consists in whatever is described by or is included withinthe terms or scope of the appended claims.

In the accompanying drawings:

` Fig. 1 is a top plan view of a table embodying my invention;

Fig. 2 is a side elevation thereof;

Fig. 3 is an end elevation thereof.

rlhe bath tub is placed upon a fiat oblong platform, 10, which at itscenter rests upon a vertical shaft, 11, that is journalled to revolveupon a. step bearing, 12, preferably having anti-friction balls that isfixed to the longitudinal center of a beam form support, 13, which atits opposite ends has upwardly projecting arms, 14, which hang fromhorizontal pivots or shafts, 15, in standards or uprights, 16. The twostandards, 16, are connected by a pair of angles, 17.

It will be seen that the tub resting upon the platform, 10, may belturned horizontally on the vertical shaft, 11, or about a vert-ical axisand also by the lateral swinging of the support, 13, on the horizontalshafts, 15, may be moved on a horizontal axis and thus by its motion onthese two axes any portion of its surface may be presented in the rightposition to receive the sifted material.

For rotating the platform, 10, upon the vertical axis, the verticalshaft, 11, has a bevel gear. 18, with which meshes a bevel pinion, 19,on a horizontal shaft, 20, which passes through one of the shafts, 15,which is tubular for the purpose, and beyond the adjacent standard, 16,has a hand wheel, 21, for revolving the shaft. Upon the tubular shaft,15, to which the adjacent arm, 14;, is fixed is a worm gear, 22, engagedby a worm, 23, on a horizontal shaft, 24, supported by a bracket orextension, of the adjacent standard, 16, upon which shaft, 24, is a handwheel, 25, by which the worm may be revolved and thus the tub supportingplatform,

10, by the swinging of the support, 13, may be tilted to the desiredposition. The worm gearing besides being an easily operated and powerfultype of gearing has the further advantage that the meshing of the wheelwith the worm holds the tub supportingl upon a horizontal axis, avertical shaft extending above said member between the ends thereof,gearing for swinging said supporting member comprising a worm, manualmeans to turn the worm, a worm wheel, a tubular shaft to which the wormwheel is fixed and gear for rotating said shaft comprising a horizontalcrank-operated shaft extending through said tubular shaft.

2. A work-table comprising a work receiving platform, a vertical shaftat or near the center thereof, a horizontal beam below said platformhaving a stepped bearing for said shaft, pivots from which said beam issuspended at opposite ends, one of said pivots being tubular, a shaftpassing through the tubular shaft and geared to said vertical shaft, aworm wheel on said tubular shaft and a worm meshing with said wheel.

3. A worktable comprising a work-receiving platform, a vertical shaft ator near the center thereof, a. horizontal beam below said platformhaving on its upper side a stepped bearing for said shaft, the shaftbeing sit-uated between said beam and said platform, a bevel gear onsaid vertical shaft, a pinion meshing with said gear, a horizontal shaftto which said pinion is secured which lies between said platform andsaid beam, pivots from which said beam is suspended, one of said pivotsbeing tubular, and said horizontal shaft extending through the tubularpivot, gearing for swinging said beam, and gearing for rotating saidhorizontal shaft.

In testimony whereof I hereunto affix my signature.
